Meanwhile high pressure over Europe is blasting warm air through the south east of the country, causing temperatures to soar.

This means the country will largely be split in two over the next few days, with wet weather dominating in the north and dry in the south.

NORTH-SOUTH DIVIDE: Battling weather front will split the nation in two in the coming days

Aiden McGivern, Met Office meteorologist, said: “We have low pressure close to Iceland and high pressure over the continent and sandwiched in between over the UK something called a waving weather front.

“Now that is simply a cold front that develops a kink, a warm front that tries to push the front in the opposite direction.

“It makes it slow, it makes it erratic in its movement and often produces bouts of fairly heavy rainfall.”

Western regions of Scotland, Northern Ireland and northern England are expected to be hit with heavy rain and strong winds today.

“We end up in a battleground situation.”

As low pressure sweeps eastwards across the nation, downpours will soak central areas later on.

The wet weather will fade away as it reaches eastern areas and meets high pressure from the south.

This pattern of low pressure colliding with high will be repeated into next week, according to forecasters.

Mr McGivern said: “We end up in a battleground situation where low pressure will want to throw weather fronts our way throughout next week but high pressure will block those weather fronts from moving in. We are right on the boundary between the two.”

Forecaster Emma Salter said: "On Sunday we could get up to 21C in parts of the country and this is largely due to the polar airflow switching to bring in the remnants of some post-tropical air.

"Temperatures will creep up over the next few days and it will feel warmer compared to last weekend which brought some air frost.

"While it will feel mild, it is not going to be all sunshine and there will be a lot of cloud about, with some strong winds and rain in the north."

WARMING UP: Temperatures are expected to soar to around 21C this weekend

James Madden, forecaster for Exacta Weather, said good spells of sunshine could push temperatures past the 21C mark through the end of the month.

He said: "We will see a significant weather pattern change to warmer and more settled weather conditions for many parts of the country.

"This will pave the way for high pressure to build across our shores delivering some prolonged Indian summer type weather that could see temperatures ranging in the mid to high 20s later in the month."
